Graph a line that would be parallel to $$f\left(x\right)=-\frac{2}{3}x$$ and has a y-intercept of -5.

Graph a line perpendicular to $$g\left(x\right)=-5x+1$$ that has a y-intercept of 4.

Graph a line coincident to $$y=-\frac{9}{3}x-\frac{8}{4}$$

What is the solution to the system? Write your answer as an ordered pair (x,y) with no spaces.
